These packages give you a CLI tool and programmatic library that runs eight health checks against any MCP server endpoint, grades the results A–F, and outputs reports in console, JSON, markdown, or HTML formats. You would adopt them to catch MCP server issues before deployment—transport negotiation failures, latency spikes, auth problems, or concurrency limits—and to enforce quality gates in CI. The engine, transport client, reporters, and observability instrumentation are separate packages that share core types and grading logic, so you can use just the CLI or compose the pieces programmatically (for example, running the engine with a custom transport and piping results into your own monitoring pipeline).
